[ laughs ] the brazil butt lift. >> i met alessandra ambrósio, and she hired me as her personal trainer. she said, "i need to lift the butt. i need to make the butt rounder and fuller." i never was approached by a supermodel and say, "i want to work the butt, but not bulk the legs." and it really challenged me to figure out how to work the butt and not get the legs bulky. so i put out this combination of ballet, capoeira, afro brazilian to make a really fun workout very effective. >> i could see results right away. you know, if i work out with him for a week, i don't have to work out with anybody else for a year. >> announcer: and today, brazil butt lift is the hottest workout in new york city's elite heal clubs. it's been featured in every major magazine, and its five-star rating have made it a social-media phenomenon on facebook, twitter, and youtube. >> i definitely wanted to lift my butt, to trim and tone the inner thighs, the saddlebags. wit
